Which of the following do supervised AI learning models PRIMARILY use to train algorithms?

Supervised learning is a foundational type of machine learning in which the model is trained on a labeled dataset. According to the AAIA™ Study Guide, labeled data includes input features along with the correct output, enabling the model to learn the mapping function accurately.

“In supervised learning, models learn from input-output pairs provided in the training data. This method enables predictive modeling tasks such as classification and regression.”

Unlabeled data (A) is used in unsupervised learning; clustered data (B) is a technique rather than a data type; and randomized data (D) refers to distribution strategy, not labeling. Hence, labeled data is the correct answer.
